The SHORTZ and LONGZ computer programs are designed to calculate the short-term and long-term ground-level pollutant concentrations produced at large number of receptors by emissions from multiple stack, building and area sources. SHORTZ and LONGZ are applicable in either rural or urban areas of both flat and complex terrain. SHORTZ and LONGZ are written in FORTRAN and are specifically designed for use on UNIVAC 1110 (or other UNIVAC 1100 series) computer. Both programs require a random-access mass storage device. SHORTZ requires approximately 55K words of core and LONGZ requires approximately 50K words of core. The LONGZ and SHORTZ source codes are respectively contained on Files 1 and 2 of Reel No. 19539. File 3 contains the source code for the SHORTZ meteorological pre-processor program METZ, which is designed for use with National Weather Service (NWS) surface and upper-air data. The LONGZ and SHORTZ example problems are contained on Files 4 and 5, respectively.
